FLOOR CLEANING AND POLISHING MACHINE.

, Specification of Letters Patent.

Patented Apr. 16, 1918..

Application filed August 11, 1917. Serial No. 185,658.

arrangement of parts described and claimed,

distinctive features being the use of a counterpoise weight forregulating the peripheral pressure exerted by the cylmdrlcal brush onthe surface with which it contacts, and the collection and storage, bypartial vacuum, of particles precipltated by the brush,-the latter and te suction means being driven by the same motor, all as heremaftermorefully set forth.

In the accompanyin drawings,

Figure 1, is a plan a paratus embodying the essential features 0 myinvention, the upper portion of the handle being broken ewa 2, is afront elevation of the parts shown in Fig. 1; I

Fig. 3, is a side elevation of the parts shown in Fig. 1, projecteddirectly therefrom, and showing the handle complete.

The truck frame A, is $11 ported in front by the axle b, of thecylindrical brush B, the

1 latter performing the double function of floor rest, as well as of asweeping polishing, or scrubbing brush. The rear of the truck frame A,is su ported on rollers r, r, the journals of which rest in bearingsformed for "them in the housings a, a, positioned at the rear corners ofsaid truck frame A These rollers r, r, are in alinement and constitutevirtually the fulcrum of the lever H, which in turn constitutes thehandle b which the truck A, is manipulated. On thls hand lever H, isadjustably secured a counterwei ht W, by which the peripheral pressure 0contact of the brush with thejioor may be regulated to suit variousconditions and requirements of use. Thus by loosenm the set screw to,the weight may be move toward or from the axes of the rollers r, r, andsecured in an desired or prescribed po- -sition on the hen lever H,between the curve .h and the switch box h, (Fig. 3). Obviously if theweight W, is positioned as shown in solid lines in the drawings it willexert greater leverage to relieve the peripheral pressure of the brushB, on the floor than if said weight W, is positioned, say, as shown indotted lines in Fig. 3, in which the leverage will be decreased and theperipheral pressure exertedby the brush increased.

The brush B, is rotated clock-wise, or with the line of travel, that is,forwardly and upwardly, by a motor M, mounted on the truck frame A, andpreferably of the electrical type, the wires thereto extending from theswitch box h, through the hollowhand lever H, and from said switchbox kby suitable cable to a source of electrical supply in a manner wellknown in the. art. Thus in the drawings the armature shaft m, isprovided with a sprocket wheel m, which actuates a sprocket chain n,engaging with a sprocket wheel 6', 0n the axle b, of the brush B, itbeing understood that the said brush is secured to rotate with said axleb.

As before intlmated the brush is rotated forward and upward as indicatedby the arrows, and consequently dust is prO ected-v nozzle e, of asuction tube e, across the lower front of the brush .13, adjacent to theline of contact of the brush with the floor as shown more particularlyin Fig. 3, so that such dust and extraneous matter is immediatelycollected and withdrawn from beneath the brush instead of beingprecipitated into the space in front thereof to be dissipated throughthe atmos here.

The suction tu e 6', extends over the brush B, to an exhaust fan orequivalent E, by which the dust, etc., is delivered to a receptacle orcontainer C, adapted to retain solid matter while allowing the escape ofair, This container C, may be of any desired form and construction, andis herein represented only symbolically as a means of receiving thedischarge from the suction device E. v

The latter is driven directly by the motor M, by means of bevel gearingas shown in Fig. 1, of the drawings, or by any other mechanicalexpedient adapted to transmit power from the motor M, to the exhaustdevice E.

What I claim as my invention and desire to secure by Letters Patent is,

Floor cl aning and olishing pp r s f the character designated,eomprisiln a truck frame, a cylindrical brush moume on the forwardportion thereofend supporting said forward portion, e suction nozzlepositioned in from: of and in close proximity to said brush andconnected withan exhaust device,

said exhaust device supported by said truck frame, a motor mounted onsaid truck frame, means for rotating said brush forwardly and upwardlyand driving said exhaust device simultaneously by power derived fromsaid motor, e fulcrum roller suppose for the rear portion of said truckframe, a. hand levee attached to and extending rearward from said truckframe and beyond the said iulci'um roller support, and an adjustablecounter- Weight on said hand lever:- for the purpose described.
